APPARATUS FOR SEPARATING GREASE FROM STEAM.

SPECIFICATION ibrming part of Letters Patent No. 692,415, dated February4, 1902. Application filed September 9, 1901. Serial No. 74,828. (Nomodel.)

To all whom it may concern.-

Be it known that 1, WILLIAM JAMES BAKER, a subject of the King of GreatBritain, residing at Peasholme House, Scarborough, in the county ofYork, England, have invented new and useful Improvements in and Relatingto Apparatus for Separating Grease from Steam, of which the following isa specification.

This invention relates partly to improvements upon the inventiondescribed in the specification of British Letters Patent granted to meand dated the 28th day of June, 1897, No. 15,384, and has for its objectthe cooling of superheated steam either immediately before it enters anoil-separator or as soon as it has entered and before coming in contactwith the baftlers, to which the grease adheres.

WVhen superheated steam at a high temperature is passed through aseparator, especially when a vacuum exists therein, no condensation ofthe steam takes place and very little oil is separated, the heat of thegaseous steam being imparted to the shell and batfiers, and any liquidor vapor is dried up. By the introduction of a jet of cold water in themanner hereinafter described the temperature of steam entering or withinthe separator is lowered and resaturation of the steam with water oraqueous vapor takes place and the steam is brought into a more suitablestate for the easy separation of the contained lubricating-oil. At thesame time the sprayed water is converted into steam and adds to the bulkof water formed in the condenser, the impurities formerly existing inthe water used for spraying being caught and drawn oif with the greasywater from the bottom of the separator.

In the accompanying drawings, Figures 1 and 2 are sectional elevationsof two forms of separators made according to the invention. Figs. 3 and4 are respectively a sectional elevation and a plan of a further form ofmy separator. Figs. 5 and 6 are views similar to Figs. 3 and at ofanother modification. Figs. 7 and 8 are sectional elevationsillustrating two further modifications.

In the arrangement shown in Fig. 1, Ct represents the shell of theseparator, and Z) the separated grease and water. c is a plain jet, theflow of cold water through the said jet being regulated by means of thevalve d. In

this case the stream of water also cools the deflector e, which assistsin lowering the temperature of the steam, which passes in the directionshown by the arrows.

In Fig. 2 instead of a plain jet a perforated tube 0 is employed, theaction being similar to that of the plain jet shown in Fig. 1.

In Figs. 3 and 4 the perforated sprayingtube 0 is carried across thefront of the angleiron baftlersfor other baftlin g surfaces which may beemployed, the said bafliers being cooled by the spray from the tube 0,whereby the temperature of steam coming in contact with them is loweredand a certain amount ofresaturation of the steam takes place,whiel1results in a larger volume of purified steam being available forcondensation.

In Figs. 5 and 6 cooling'tubes g g are represented, between Which steampasses to the baffiers. Through these tubes a current of cold water.flows, the flow being regulated at the valve d and the temperature ofthe steam being reduced by coming in contact with the tubes. Other rowsof tubes may be added if it is desired to further reduce the temperatureof the steam, and the heated water passing out of these tubes may beused as boilerfeed water.

In the arrangements shown in Figs. 7 and 8 the temperature of the steamis reduced before it enters the separator-in Fig. 7 by inserted in thebranch h, attached to the separator, as shown, or in the exhaust-steampipe near the branch, and in Fig. 8 by means of a cold-waterjacketi,which cools the steam passing through the length of exhaust-steam pipe,the inlet for cooling-water being represented atj andthe outlet for thesame Water as it becomes heated and rises atj.

Having now particularlydescribed and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. In apparatus for separating oil or other grease fromsteam, the combination with the easing into which the steam isintroduced, provided with an inlet and outlet, and With means fordeflecting the steam between said inlet and outlet, of a device forlowering the temperature of the steam located adjacent to the inlet tosaid casing to facilitate the sepmeans of a jet or spray c, which maybe' aration of the oil or grease, substantially as described.

2. In apparatus for separating oil or other grease from steam, thecombination with the easing into which the steam is introduced, providedwith an inlet and outlet, and with means for deflecting the steambetween said inlet and outlet, of a Water-pipe located in the path ofthe steam adjacent to the inlet to said casing to reduce the temperatureof the steam to facilitate the separation of oil and grease,substantially as described.

3. In apparatus for separating oil or other grease from steam, thecombination with the casing into which the steam is introduced, providedwith an inlet and outlet, and with means for deflecting the steambetween said inlet and outlet, of a water-injecting device, locatedadjacent to said inlet and discharging directlyinto the steam, to lowerthe temperature of the steam and facilitate the separation of oil andgrease, substantially as described.

4. In apparatus for separating oil and other grease from steam, thecombination with the easing into which the steam is introduced, providedwith an inlet, an outlet and a deflecting device between the inlet andoutlet, of a water-injecting device located adjacent to said inlet anddischarging against said defleeting device, for cooling the steam andfacilitating the separation of oil and grease therefrom, substantiallyas described.

5. In apparatus for separating oil and other grease from steam, thecombination with the easing into which the steam is introduced, providedwith an inlet, anoutlet, a deflecting device adjacent to the inlet and aseries of baffle-plates in the casing, of a water-injecting devicelocated in said casing and discharging against said baffle-plates tocool the steam and facilitate the separation of oil and greasetherefrom, substantially as described.
